TOTAL-TAKING DEVICE.

Application iled January 22, 1926., Serial No This invent-ion pertainsto record controlled tabulating machines, having an improvement on themachine disclosed in Canadian Patent No. 247 ,815, March 17,1925,'issued to F; MQCarroll, and copend-ing United Statesv application,Serial No. 607 ,847 tiled December 19, 1922, by the same inventor.

One function of that machine isto ac! cumulate in two accumulatorestatistical data from a single field of perforated record cards,

and to print minor, or sub, totals and major,

or grand, totals from the two accumulatore,

under the automatic control of group perforations in the cards. The sameamounts are added in t'W'O accumulators, one handling minor totalsandthe other major totals.

- Whenja sub group cont-rol designation changes,

a total is taken from the sub total accumulator and that accumulatoriscleared or zeroized.

The taking of a minor total does not affect the major total accumulator,which continuesI to add all amounts,

changes, until a major group designation f changes, whereupon a majortotal is taken and the major accumulator cleared, or reset.

Whenever changes of major and minor group designations occursimultaneously, the

' machine prints either the minor or major total, but does not printboth totals, and the principal object of the present invention is toprovide improved devices which will enable the machine to print bothminor and major totals whenever the 'minor and major group controldesignations change at the same time. Briefly, this result is broughtabout by first printing the minor total and then, if a major group haschanged, causing the machine to perform an extra revolution during whichthe major total 1s printed. Each accumulator 1s Fig. 1 is a sidesectional elevation of the machine, showing accumulators, printingmechanism, etc. n

Fig. 3 is'a plan view of the mechanism shown inFig, 2.' l 50 Fig. 4 is awiring diagram of the electric my invention. l `Provision fisvrriade fortaking major and regardless of minor groupA ytion it' will lower sets ofvtaneously sensethe group control perforations of two successivecards.

' HEJ UED 82,933, and in Great Britain February minor totals from thesame record cards. The upper shaft 249 (Fig. 1) drives the major totalaccumulator,

.The accumulators are `arranged in two banks, the upper accumulatorsbeing designated generally 253 and the lower accumulators beingdesignated generally as 254.

Located above the accumulators is the printing drum carried on shattll.The drum carries a number of ty-pe levers 162, one row of type leversbeing provided for each column 4on the card, and the number ot' the typelevers 05 about thedrum periphery corresponding to thev index' pointperforations in the card column. These type levers, when engaged by thecontrolling hook members;` 163, cause the type to be thrown upwardly toprint on the 'record sheet on the platen.

To control the operation of the type levers 162 for listing items,call-magnets 165 are provided with individual armatures which control-and elevate call-wires 166 which ex- 75 tend upwardly and control theprinting devices.

Extendingdow. wardly from the printer cont-rol mechanism are call-wires240, each of whichy actuates A an accumulator element lthrougha member266 to add on that element the amount printed by the type bars to whichnthat accumulator element is correlated.

A All Athe above mechanism, together with the group controldevices, isfully described 35 inthe patent and application above referred to. Forthe` urpose of the present descripe Lsuiiicient to know that the groupcontrol devices comprise upper and contact brushes which simuloo l Ifthe perforations are different in the two cards itmeans that a changeofgrou'p has occurred, whereupon the total taking mechanism is broughtinto action, o5

aswillappear. When a total is to be taken l the total clutch magnet-323is energized and causes vertical shaft 315 to be turned concurrentlywith. the printing drum. Directly below the total-clutch magnet 323. aretwo 10o lmagnets 908 and 903, theformerbeingthe grand total controllingmagnet and the latter a grand-total pre-selecting magnet. The

magnet operates upon an armature 326,

and the lower shaft 250 drives '55 the minor total accumulator.

It may be explained that the so-callcd total clutch controlled by thetotal clutch magnet, is a clutch of the one revolution type permittingshaft 315 normally to make one revolution only, although oit' course itwill make more than one successive revolution if the magnet 323 isre-energized at the proper times. Furthermore the gearing is such thatthe shafts 315, 329 and 331 will rotate once in the same time.

Beneath the pre-selecting magnet 903 is pivoted an armature 905 (Figs. 2and 3) normally held in'its lower position by a spring 921 and having aforkedend-which embraces a groove in a double dog-clutch member 940splined to a vertical shaft 941 mounted to rotate in suitable upper andlower bearing lates. This shaft has secured to it at its ower end agear-wheel 942 in .mesh with an idler 952 which is in mesh with agear-wheel 962 secured to the lower end of the shaft 315,

7 the gear ratio being 1 1.

Theshaft 941 also carries two gear-wheels 943 and 944 provided on theirhubs with clutch teetheapable of being engaged by the clutch teeth ofthe member 940. These wheels 943 and 944 are normally free to rotateupon the shaft 941, and are clutched thereto by the engagement therewithof the clutch member 940, the wheel 943bein so clutched when the magnet903 is deenerglzed and the wheel 944 when the magnet is energized, aswill be readily understood. l

A vertical cam-shaft 950 is mounted in bearings adjacent the shaft 941,and has secured to it two gear-wheels 943e and 944e in mesh with thewheels 943 and 944, respectively. The ratio of the wheels 943 and 943eis 1:1, and the ratio of the other pair is 221.1

Thus when the magnet 903 is deenergized, one revolution of the shaft 315will cause the cam-shaft 950 to make one revolution, but when the magnet903 is energized' the camshaft will only turn through one-half arevolution.V

The shaft 950 carries a cam 950anf insulating material having one highpoint which en; gages and closes momentarily a pair of normally opencontacts 478 to berefer'red to hereinafter. Another pair of normallyopen contacts 907 are provided which are closed when the magnet 903 isenergized by a rod fixed to or not. For example, Vcessivel mam groupsrepresentmg two railand extending upwardly from the armature 905.

A third pair of contacts 910 are provided which are closed momentarily,by a cam 909 secured to the shaft 331, just prior to the end of therotation of the shaft 331.

The parts j ust described with reference to Figs. 2 and 3 operate todetermine whether a sub-total only, or a sub-total followed by a grandtotal, shall be taken as will hereinafter bc describe The details of thetotal taking mechanism and its operation are fully explained in theabove patent and application, and it will be sulicient for the presentpurpose to know that shaft 329 is caused to make one revolution wheny amajor total is to be taken, and shaft 331 must make one revolution whena minor total is taken. The total taking operations carried out byshafts 329 and 331 include the resetting of the accumulators.

In' the diagram (Fig. 4) brushes 480 are the tabulating brushes; upperand lower brushes 144 and 145 are the group control brushes for minorgroups, while upper and lower .brushes 144@ and l45a are for major groupcontrol. 503 ,and 503e are the minor and major group control magnets,respectively. 482 is the plug board by means of which desired circuitconnections are made.

So long as the machine is running and successive cards correspond so farastheir group designations are concerned, both magnets 521 and 515 willbe energized. When a change in either a minor or major group occurs, oneor the other of these magnets 521, 515 will be deenergized.

It is the relay circuit marked 523 of these two magnets 515 and 521which maintains the energization ofthe card :feed clutch magnet 95.Consequently, after the circuit 523 is broken by either relay, the cardfeed clutch magnet will become deenergized at the proplun er time in thecycle andsubsequently a minor or major total will be taken, depen ingupon the energization of the magnets 908, 903, as will beA explained. y

The mannerv in which it is determine-d whether a sub-total only, or asub-total and a grand total, shall be printed will first be described. yi

It should be explained thatna sub-total is always required when a grandtotal is taken, whether the `sub-group 'perforations change there may betwo sue.-l

ways A and B. Each mam group will usually comprise several sub-groupseach relating,

maybe, to a commodity such as coal or oil.

If the last sub group of main group A is coal and the first sub-group ofmain group Bis oil, then the sub-group and main group perorations willchange simultaneously. If the last sub-group of A is coal andthe firstsub-group of B ,is alsoA coal, then the subgroup perforations will notchange. Buta. sub-group total of As coal must be taken,

and the sub-group accumulator-cleared, be-

fore the machine re-starts to tabulate Bs ,cards, otherwise As coal willbe added to Bs next sub-total.

Consequently, whenever the machine. stops as a result of a change ofgroup perforations, whether sub-group or main group or both, a sub totalmust a grand total only if the main group perfora tions have changed.Reverting now to Figs. 2 and 3, it will be noted that the springs 920normally hold the clutch-sleeve 327 in its lower position to clutch thesub-group accumulator shaft 331 to the resetting shaft 315. Only whenthe magnet 908 is energized is the clutch-sleeve raised by armature 326to clutch th main group accumulator shaft 329 to the shaft 315.

Consequently it is necessary to energize the magnet 908 (when a grandtotal is to be printed) at the end of one revolution. of the shaft 315and to provide for a second revolution of the latter. If `no grand totalis to be printed the magnet 908-is not energized and the shaft 315 needonly-make one revolution.

When a change occurs' in the sub-group perforations only, the magnet 515(Fig. 4) is deenergized and consequently the card-feed is stoppe-d aspreviously known forconvenience -as E cams, function to cause thetotal-taking and resetting shaft 315 to rotate, as is fully described inthe above mentioned patent and application.- As the main groupperforations have not changed, the magnet 521 is energized and attractsan armature 900 (Fig. 4), thereby opening acirciiit A-'B in which isplaced the winding of the magnet 903 shown i-n Fig. 2 and known as thegrand Atotal pre-selecting magnet. The armature 905 ofthis magnettherefore remains in its lower position, clutch-member 940 in engagementwith the gearwheel 943. Consequentl the cam-shaft 950 rotates onceduring thesingle revolution` of the shaft 315. As will be seen from'Fig.

f 3, the winding of the grond-total controllin Y I 4magnet 908'` (whichmust be energized as a ready stated to take a grandtotal) is inl acircuit CD containin the contacts 907 which are closed-only w en themagnet 903 the single revolutionv is energized. Consequently the magnet908 will not be energize'd,.the sleeve 327 will ref main in its lowerposition and. only awsubf total will be taken. Just rior to' the end ofof t e shafts the cam 909 closes the contacts 910 in the circuit C-D,but as the contacts 907 remain open themagnet 908 remains neverthelessdeenergized.

. The cam950a will close the contacts 478 at the end of the sin le lrevolution thereby 'reenergizing the car -feed clutch-magnet andstopping the action'of the Ev cams,as previously` described, and themachine will conbe printed, to be followed by described and cams, y'

retaining the will be noted that only one total taking and resettingcycle has been performed.

Should the 'main groupv perforations change, but not thesub-groupperforations. the magnet 521' will be vdeenergized (stoppin gthecard-feed as previously explained) and the armature 900 will not beattracted. There willtherefore be acircuit.` from A through cam contacts901 (closedrjirst prior to the stoppage of the card-feed) contacts 900,relay .902, grand-total preselecting magnet 903 to B, this circuit beingmaintained by the closure of contacts 904 (prior to the stoppage of thecard-feed) and armature of re lay 902. i

The energized magnet 903 will raise its armature.905, closingthecontacts 907 and throwing the clutch-member` 940 into engagement withthe gear-wheel 944. The sleeve 327 being still in its lower positionand-the total controlling magnet 908-'will be com! plated, thus raisingthe clutch-sleeve 327v and placing the grand-total accumulator shaft 3291n gear, with the. shaft 31,5; this circuit C-D being held closed (inspite'of the reopening of contacts910) by a holding relay I 912, as willbe apparent'from' Fig. v4. Since the contacts 478 are still open, the Ecams will still function and a second revolution of the shaft 315 willoccur,thus taking a grand total. At the end of this second revolution.the cam 950e will close the contacts 478 momentarily and therebyre-en'ergize the card-feedcliitch magnet '95,V thus starting a' newtabulating operation on the cards of the next main group and stoppingthe actionof the E cams.

. The cam-contacts 911 will thereupon open` thus deenergizingthe magnet908 and the relay 912, and the armature 326willcease to be attracted.Consequently the spring 920 will return the clutchsleeve 327 to itslower position, thus disengaging the grand-total accumulator. andplacing the sub-.total accumulator in gear with the shaft 3,15 inreadiness for the next sub-total taking operation.

Further,`as'soon as the card-feed kis resumed, the `cam contacts 904will open, thus deenergizing the holding relay 902 and thepre-selectingl magnet 903, the armature 905 will be returned to normalbyits spring-92.1

and the clutch-member 940will move out of engagement with the gearfwheel944 and reengage 'with Vthe gearwheel 943. All the parts are thereforereturned to their original position in readinessfor the taking of thenext sub-total. f

`-lt Will be apparent that if the sub-group pertorations change at thesame time as the main-group p ertorations the sequence of operationswill be the same as has been described for a change of main-groupperforations only, since a change of sub-group perforations does notalter the position of the'clutch- Sleeve S27-that is to say, a sub-totalwill first be taken and afterwards ay grand total, followed by a returnof all the parts to normal.
